No filters. However, they were shot with my professional lens (200mm 2.8 prime), the only one in my bag, and it has a very nice color rendition, better than the zoom I usually shoot with. These were shot from the little pier that juts out into the harbor that you can reach from the boat launch parking lot. The only thing I did, like I usually do in post processing, is my camera has a tendency to shoot dark, so I have to lighten up with levels in the mid-tone range and then I bump the saturation 15 points or so to compensate for the loss of color in lightening the image. The color was very intense and when my viewscreen popped up with the preview image after the shutter closed and the color was that intense I knew I had a good night.
